枸杞多糖对篮球专业大学生免疫功能的影响

Impact of lycium barbarum polysaccharides supplementation on immune function in students major in basketball

目的探讨枸杞多糖(LBP)对篮球专业大学生免疫功能的影响。方法将20名男子篮球专业大学生随机分为对照组和试验组,每组10人,2组运动员均进行心率每分钟180～190次强度的运动训练,正常饮食。连续训练21 d,期间试验组每日早晚各服用LBP,每次2粒,每日2次;对照组每日早晚各服用等剂量安慰剂(内含淀粉)。训练前后分别检测免疫指标IgA、IgG、IgM和CD4+、CD8+、CD4+/CD8+值。结果试验组训练后IgA及IgM浓度明显高于训练前,并且高于对照组训练后IgA及IgM值,差别均有统计学意义(P<0.05)。试验组训练后CD4+及CD4+/CD8+比值较训练前均明显升高,且明显高于对照组训练后CD4+及CD4+/CD8+比值,差别均有统计学意义(P<0.05)。结论 LBP能改善篮球运动员的免疫功能。

Objective To study the impact of lycium barbarum polysaccharides（LBP） on immune function in college students major in basketball.Methods Twenty men′s basketball subject college students were randomly divided into control group and experimental group,and each group for 10 persons.Athletes were trained by 180-190 times per minute heart rate of exercise training in two group,normal diet.All players performed exercise everyday for 21 days.LBP 4 g were took experimental group and placebo（containing starch） 4 g were took in control group during the each day of the daily morning and evening.Values of immune parameters IgA,IgG,IgM,and CD4＋,CD8＋,CD4＋/CD8＋ were measured before and after experiment.Results Values of IgA and IgM after the experiment were significantly higher than those before the experiment in experimental group,and higher than those in control group;The difference was statistically significant（P〈0.05）.CD4＋ and CD4＋/CD8＋ ratio after the experiment were significantly higher than those before the experiment in experimental group,and were significantly higher CD4＋ and CD4＋ / CD8＋ ratio in control group,the difference was statistically significant（P〈0.05）.Conclusion LBP could improve the immune function of college students major in basketball.
